The situation is beyond our expectation. Lei Zhentian and Lei Zhenyu discuss it in a low voice. Then they say to Jiang Huawen, ”elder Jiang, I don't know how long this passage is?”
Jiang Huawen looks at Fang Yang, who immediately knows that this is to let himself say: ”judging from the last entry, the total length of the passage is about 100 Zhang.
However, it should be noted that if gunpowder is used, it is better not to be too powerful, so as not to collapse the cave wall and damage the overall structure of the treasure. ”
”Nearly 100 Zhang It can't be too powerful to destroy the whole structure of the treasure.... ” Lei Zhentian made a general calculation in his mind:
”it seems that the thunderbolt bombs on our bodies can't be used any more. They are all powerful guys. They need to be reconstituted.”
Jiang Huawen asked, ”how long does it take to prepare? How long will it take to get through such a channel? ”
Lei Zhentian confidently said: ”I can directly let people air drop the materials. As long as the materials are in place, the channel can be opened in one day at most, and the structure of the treasure will not be damaged!”
Jiang Huawen nodded: ”it's so good. Please get ready.”
”Well, we'll go back and get ready.” Lei Zhentian said and left with Lei Zhenyu.
Popper was a little worried: ”is it really going to explode with gunpowder? If the dosage is not well controlled, the consequences will be unimaginable! ”
Fang Yang comforted: ”don't worry, thunderbolt hall is the ancestor of gunpowder. The gunpowder they made can flatten a mountain and break a mosquito's leg.As for the proportion of gunpowder dosage, if thunderbolt Hall says that it is the second, no one in the world dares to be the first! ”
If someone else, pop may be unconvinced, but Fang Yang talks, then he has no temper at all.
Two hours later, a small plane flew over and dropped several large boxes. Immediately, people from thunderbolt hall put the boxes away and carried them directly to the entrance.
Lei Zhentian and Lei Zhenyu temporarily set up a tent here, not only to make the dosage of explosives more accurate, but also for confidentiality.
After all, the proportion of gunpowder is the secret of thunderbolt hall. For hundreds of years, I have been living by this.
More than ten minutes later, Lei Zhenyu came out and said to Jiang Huawen, ”please stand back. I need to blow up the basalt above and determine the size of the entrance before I can continue dispensing.”
”Yes.” Jiang Huawen and all of them got married, leaving enough space for the people of thunderbolt hall.
Fang Yang is still very interested in the thunderbolt hall. It's definitely not a simple thing to be able to gain a foothold in the ancient martial arts world with just a small thunderbolt bullet.
Lei Zhenyu first marked the center point, then radial, hit dozens of small eyes, put a black ball into it, and connected the small eyes with white powder.
After finishing, Lei Zhenyu took out a refractor and set the white powder on fire. Only a slight explosion was heard one after another. After the choking smoke, the hard ground was full of cracks.
As soon as Lei Zhenyu waved, some disciples came forward to clean up the gravel. Soon, the entrance of the underground palace was exposed.
Fang Yang had a look. As expected, the whole passage of the underground palace was blocked by basalt.
Lei Zhentian came out of the tent, murmured to Lei Zhenyu for a while, and got into the tent together. After a few minutes, he came over with a few black balls,
now Fang Yang knows that this thing is the legendary thunderbolt bullet. It's almost like sheep manure, but it doesn't take much time to beautify.
Each thunderbolt bullet hit the basalt at the entrance, only splitting the rock, but it didn't completely shake it. It seems that it is not powerful enough.
